During field work in the summer and fall of 2013, mineral soil samples were collected in a grid of 6x6km in Nord-Trøndelag and Sør-Trøndelag’s municipalities of Trondheim and Malvik as well as on the Fosen peninsula. Together with samples for quality control, the <2mm fraction of samples from 752 locations were digested by aqua regia and analyzed for 57 elements.

MAREANO has mapped Norwegian waters for ten years, and produced several map series at different scales addressing bathymetry, geology, biology and pollution. There has been an increasing demand to document the confidence of these maps, and to evaluate the effectiveness of the present survey strategy in relation to these map products.

Forkortet: The sedimentary sequence in the subsurface of the Trøndelag Platform (Mid-Norway) has been assessed with regard to its suitability for long-term storage of CO2. This study is part of the EU-funded CO2STORE project and was stimulated by the geopgraphical proximity of the Trøndelag Platform to planned CO2 point sources in Mid Norway.

This report presents an overview of programs that can be used for analytical and numerical hydrogeological modelling. The overview is not intended to be a complete list but an attempt has been made to include many of the most used and popular program available today within hydrogeological and geochemical modelling.

NGU conducted an airborne magnetic and radiometric survey in Kinsarvik area in July and August 2015. The primary purpose of the survey was to see if there is uranium bearing bedrock in and next to Kinsarvik where there are great problems related to high indoor radon concentrations.
This report describes and documents the acquisition, processing and visualization of recorded datasets. The geophysical survey results reported herein are from 400 line km, covering an area of 80 km2.

The report documents the lithologies and molybdenite mineralization exposed in underground mines of the Knaben molybdenum (Mo) mining district in Kvinesdal, Vest-Agder, SW Norway. Scanning electron microscope cathodoluminescence (SEM-CL) and trace element analyses of quartz by laser ablation inductively coupled mass Spectrometry (LA-ICP-MS) were performed on 37 quartz and quartz-bearing samples in order to better understand the P-T conditions during magma emplacement and Mo-mineralization.

NGU conducted an airborne magnetic and radiometric survey at Kviteseid, Nissedal, Fyresdal and Dalen, Telemark county in June 2015 as a part of the MINS project (Mineral resources in Southern Norway). This report describes and documents the acquisition, processing and isualization of recorded datasets. The geophysical survey results reported herein are approximately 7340 line km, covering an area of approximately 1468 km2.

This technical report describes the method used to draw the susceptibility maps for rock falls in Norway. In order to cover the entire territory of Norway, a fully-automatic GIS-based solution was developed and applied. Input data are the gridded digital elevation model of Norway at 25 meter cell size, a bedrock geological map and a quaternary map.

As part of a method development initiative in the MAREANO seabed mapping programme (www.mareano.no) a pilot survey using Underwater Hyperspectral lmagery (UHI) was undertaken in Trondheimsfjorden during December 2014.

Aeromagnetic data from the Røst Basin (RAS-03) were acquired in 2003 and compiled with neighbouring data-sets. The new Ra 3 compilation (Røst Aeromagnetics 2003 consisting of LAS-89, NAS-94, VAS-98 and RAS-3) has been reprocessed and subsequently merged with the SPT-93, NGU-69, NGU-73 and NRL-73 surveys in addition to the mainland of Norway aeromagnetic grid data. A compilation of the existing gravity data in the area has also been carried out.

The field trip of the 3rd Slope Tectonics conference visits areas of past rock slope failures and present-day unstable rock slopes and aims to discuss the structural and geological conditions of these sites, the morphologies and tectonic fabrics induced by slope movements and the role of glaciers, isostatic uplift and major faults in the development of rock slope failures.

The 3rd Slope Tectonic Conference arranged at the Geological Survey of Norway on September 8.-12. 2014, follows the 2nd Slope Tectonic Conference organized at the Geological Survey of Austria in 2011 and the 1st Slope Tectonic conference organized at the University of Lausanne, Switzerland in 2008.

MAREANO has shown that acoustic mapping with limited ground truthing is a powerful tool for mapping biogenic mounds and associated bioclastic sediments. Standard Quaternary geology maps show the genesis of surficial sediments, i.e. the origin of the sediments and how they have been deposited. In MAREANO, maps of bottom sediment genesis (where bioclastic sediment is one of many sediment classes) are complementary to the maps of bottom sediment grain size.

Norway’s ongoing seabed mapping programme MAREANO (Marine AREA database for NOrwegian waters) includes delineation of the sea floor into large geomorphic units, which are referred to as marine landscapes. These landscape units are mapped in accordance with Version 1.0 of the nature-type classification system Nature types in Norway (Naturtyper i Norge, NiN), and the classification operates at the ‘landscape’ level of NiN.
